STORM-SASH FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 557,408, dated March31, 1896.

7 Application filed January 21, 1896. Serial No. 576,303. (No model.)

To all whom it may concern.-

Be it known that I, ANDREW A. LOETSCHER, of Dubuque, in the county ofDubuque and State of Iowa, have invented certain new and usefulImprovements in Storm-Sash Fasteners, of which the following is a full,clear, and exact description.

This invention relates particularly to devices for fastening stormwindows, screens, or shutters to a window-casing; and the object is toprovide a simple and comparatively inexpensive fastener and which may bequickly and easily operated from the inner side of a room, so that ascreen may be placed in position or removed with very little trouble.

I will describe a fastener embodying my invention and then point out thenovel features in the appended claims.

Reference is to be had to the accompanying drawings, forminga part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 shows fastening devices embodying my improvement as attached toa sash. Fig. 2 is a front View of the fastener, drawn on an enlargedscale. Fig. 3 is a back view thereof. Fig. 4 is a side view thereof, andFig. 5 is a front end view.

The fastener comprisesa block Acentrally perforated for the passage of apivot on which the block turns, and it is provided with a lever orhandle a. Extended partially around the block is a cam-flange a. Fromacentral opening a the flange is inclined toward the sash side of theblock and the ends terminate in depressions a and shoulders or stops 0..

Pins or lugs A are secured to the windowcasing A in such a manner as toextend in the transverse direction of the casing.

In use one or more fasteners may be attached to the inner face of eachside rail of the sash A When securing a sash, the same is placed againstthe outer surface or jamb of the casing, then by takinghold of thehandles a and holding them in the transverse line of the sash the pins Aare to be passed through the openings a and obviously upon turning thefasteners in either direction the cam-flanges engaging the pins willcause the sash to be drawn tightly against the frame. As the pins willenter the depression a the said depressions will form keepers to preventthe fasteners from turning accidentally to a releasing position.

Having thus described my invention, I claim as new anddesire to secureby Letters Patent- 1. A sash fastener, comprising a block adapted to bepivotally connected to a sash, a flange on said block inclined inopposite directions from a central opening, a handle opposite and inline with the opening in the flange, and a pin or lug designed to beattached to a window-casing for engagement with the flange,substantially as specified.

2. A sash-fastener, comprising a rotary block having a handle, acam-flange on the block, said flange having an opening at its centralportion and having keeper depressions at its opposite ends, and a pin orlug for engagement with the flange.
